A method of adjusting preload on a bearing assembly of a wheel mounted on an axle or spindle with a lock nut includes mounting a preload adjustment tool onto a threaded axle or spindle. The load on the bearing assembly is increased using the tool. The wheel on the axle or spindle is rotated to set the bearing assembly. The load on the bearing assembly is decreased to a desired maximum preload on the bearing. After decreasing the load on the bearing assembly to a desired maximum preload, the lock nut is tightened by hand until the lock nut cannot be further tightened. The lock nut is loosened by rotating the lock nut to a preferred location where a guide mark on the tool aligns with one mark on the lock nut located closest to the guide mark wherein a resultant preload on the bearing assembly is within a preset range from the desired maximum preload.

A multiple directional wheel including a wheel frame comprising identical component parts. Each of the wheel frame components comprise: a hub having a main axis about which the multiple directional wheel is adapted to rotate; a hub rim radially surrounding the hub; a first plurality (four shown) of peripheral roller supporting arms (“first arms”) radially extending from the hub rim and aligned in a first plane; and a second plurality of peripheral roller supporting arms (“second arms”), each member arm of the second plurality of peripheral roller supporting arms having a radially inner base and being circumferentially offset with respect to diagonally adjacent members of the first plurality of peripheral roller supporting arms. Each of the wheel frame components further comprise a plurality of beams corresponding to the number of member arms of the second plurality of peripheral roller supporting arms, each respective beam extending from the hub rim to a corresponding inner base of a member arm of the second plurality of peripheral roller supporting arms, and a plurality of spigots extending from each corresponding one of the plurality of beams or the inner bases. The second plurality of peripheral roller supporting arms lie in a second plane normal to the main axis, spaced from, and parallel to, the first plane; and each of the spigots from one of the wheel frame components is received in a recess formed in a facing surface of a complementary one of the wheel frame components to join the wheel frame components to form the wheel frame.

An axle housing assembly and a method of manufacture. A friction weld may join a spindle to an arm portion of the axle housing assembly. An extension weld may encircle the arm portion. The extension weld may extend from the friction weld in a direction that may extend away from the spindle.

A stable, low-weight wheel which is particularly suitable for high system-weight bicycles, such as electrically powered bicycles and cargo bikes, includes a hub, at least three solid-body spokes disposed rotationally symmetrical to the wheel axis, and a rim. The body of the hub, spokes and rim is made in one piece by injection molding of a glass-fiber reinforced thermoplastic. The spokes have an S-shaped cross-section with an opening angle which increases in the direction of the rim, taper from the rim towards the hub in a central cross-section of the wheel, and taper from the hub towards the rim in a wheel cross-section running through the center of least one spoke. A method for producing the wheel is also provided.

An aircraft hubcap/wheel cover which uses ambient airflow (120 mph-175 mph) to rotate wheels on the landing gear of an aircraft accomplished by using slightly protruding slats, blades, scoops or other air capturing shapes, (once the landing gear has been lowered). These air capturing shapes are integrated as part of the hubcap/wheel cover during manufacture and are directly determined by ground speed applicable to that aircraft with the ultimate purpose being tire longevity. The wheel cover hubcap is a single piece design and has no moving parts.

Provided is a hub unit bearing wherein a cover can be firmly fitted with an outer ring member, and it is difficult for foreign matter to enter inside through a water drainage hole formed in the cover. The cover that covers the inside end section in the axial direction of the hub unit bearing includes a disk section, a small-diameter cylindrical section bent in the axial direction from the outer perimeter edge section of the disk section and a large-diameter cylindrical section. A cut and raised section that is cut and raised toward the inside in the radial direction is formed in the small-diameter cylindrical section, and a water drainage hole that passes through from inside to outside the cover is provided in the portion that is cut and separated from the small-diameter cylindrical section.

Disclosed are modular mechanical assemblies formed from durable, corrosion resistant components with sufficient strength to maintain efficient operation. The modular mechanical assemblies include a novel torsion axle assembly having a cartridge that houses a torsion bar with a splined tip. A load bearing, relatively incompressible bushing is optionally disposed about the torsion bar. The cartridge is inserted into an axle tube, and an end cap is placed over the cartridge and torsion bar. The end cap is affixed to the axle tube such that the bushing is secured within a bore in the end cap. The torsion bar tip extends through the bushing and end cap and is secured within a torsion arm. A spindle is also secured within the torsion arm. One or more components of the torsion axle assembly are made from a low alloy, medium carbon steel material that provides corrosion resistance and advantageous yield and ultimate strength properties. One or more components of the assembly can also be coated to improve corrosion resistance. Suitable coating techniques include, but are not limited to liquid ferritic nitrocarburizing, gas nitriding, electroless nickel plating, or a diamond like carbon coating process.

A vehicle wheel having a rim, a hub, a plurality of spokes with at least one of the spokes having a first portion connected the rim and a second portion connected to the hub. The rim includes a spoke bed wall with a radially outboard surface and a spoke hole having a radially outboard entrance and perimeter edge. The spoke extends through the spoke hole and is engaged to the spoke bed wall by an overlie engagement at a bearing interface between a bearing surface of the spoke and the radially outboard surface to limit longitudinally inward displacement between the spoke and spoke bed wall. At least a portion of the bearing interface is laterally outwardly spaced from the first perimeter edge by a lateral distance of at least 0.7 millimeters.

The present invention provides a non-pneumatic tire which is provided with an attachment body (11) attached to an axle, a ring-shaped body (13) which surrounds the attachment body (11) from the outside in a tire radial direction, and a coupling member (15) which displaceably couples the attachment body (11) and the ring-shaped body (13), wherein the coupling member (15) is formed of a synthetic resin material and a reinforcing member is embedded in the coupling member (15).

This invention is related to a wheel securing structure of trucks. The securing structure mainly install iron screwshaft liners on keyholes of the mounting parts of the aluminum rims. The bolts of the assembling part correspondingly penetrate the holes of the screwshaft liners each. A first folded edge and a second folded edge are formed on two terminals of the screwshaft liners to respectively insert into the conical pits of the mounting part of the rims. The nuts screw onto the bolts of the assembling part to secure the rim onto the assembling part and the nuts. When the trucks pass bumping roads, the relative motion, caused by vibrations, is occurred between the rims and the assembling part. Therefore, friction is generated between the wheels and the bolts, as well as the nuts and the terminal surfaces of the assembling part. The screwshaft liner is used to let the friction above act on the screwshaft liner. Therefore, the soft aluminum rim will not be directly rubbed by the bolts, nuts, and the assemble part to be damaged. Accordingly, the aluminum rim can be suitable for the trucks and other heavy vehicles.
